What line spacing issue does Charis SIL suffer from? With ADE, I like the tight spacing. It works very well. Also, when I modified the other metrics, it works well on a Kindle.

Default Charis SIL line spacing is horrible. I don't know why the people who made the font hasn't fixed it? Gentium does not have this problem.

Typo Line Gap in a KF8 does affect line spacing.
In a Mobi Book Typo Line Gap does nothing.
Line Gap doesn't seem to do anything in KF8 or Mobi.

I did discover something else while testing.
Fonts with numbers in their name wont work on a KF8 it must be all letters. It works fine on a mobi book but not a KF8.

Okay, I have played around with the Caecilia font that I extracted from the KPW. As noted already, the KPW itself modifies the Caecilia font using some behind the scenes style sheet giving it more weight and and increased line gap.

I have added weight to the font to increase its readability at smaller sizes and where the frontlight is used at higher levels.

I am not using Font Creator since there is no version for the Mac, but have Fontographer and added 60 em to the fonts. I tried playing around with separately modifying the vertical and horizontal weights, but ended up with results that were unsightly and very hard to fix properly for the KPW.

I have also modified some of the glyphs individually after weighting to improve readability at smaller sizes. For example, the "r" often touched the edges of other glyphs like "n", which could be confused with "m"

I actually like the smaller line gap that resulted from the extracted Caecilia fonts so I did not have to change that at all.

It was interesting with the line gap changes, that the heavier weighted Caecilia at size 3 shows just as many words as the built-in Caecilia at size 2.

Does anyone know if font kerning is properly displayed on the KPW in AWZ3 formatted books? I tried searching for this answer, but did not find one and I don't want to spend time fixing up the kerning of my modified fonts if it is not supported.

I'm going to say yes because every time Amazon's updates the default fonts they add more kern pairs.

That's way beyond my level of competence. I'll just stick with what I've got. oh, well. I'd rather have the fonts list limited to fonts I'll actually use, but I guess I have to have the whole USE_ALT_FONTS list showing to get my custom fonts to be available.

Not really. If you don't mind installing KUAL, then I can write 2 buttons for it: one button to (partially) hide the extra fonts, and the other to restore to default. There will be no need to mess with usbnetwork.

If that sounds easy enough, then I will go start working on that. Going to take a bit of work, as hiding all fonts is not the best solution for everybody. I myself have all extra fonts hidden except MT Chinese Surrogate - that one is quite nice as a builtin non-fancy san-serif font with bigger weight.

I have kerned my Caecilia modified font and it does not change how the test is displayed in an AZW3 formatted book (with no publisher fonts - I ran it through calibre).

Below are two screenshots. The first is with no kerning set and the second is with manual kerning. In particular, I changed the "wr" and "ri" to have a kern value of 100 to see if it changed the word "wrinkled".

I have restarted my KPW so many times today playing with the modified Caecilia font.....

Okay well that's good to know. Perhaps it doesn't work on a custom fonts.

I should learn to read... I kept going back and forth looking for a difference, and couldn't spot one. So I finally downloaded the images and ran them through a diff program and found them to be IDENTICAL other than the location text. Then I re-read the text. :-)

Me, too!!!
@Duckietiger, can you make just ONE button that does the jailbreaking and the font removal? Sigh... Just dreaming.....

No, unfortunately not. The button requires to be already jailbroke. When I went through the config files yesterday, I found a loophole to possibly bypass the requirement of jailbreak. First quick test was unfortunately not successful, will keep digging deeper on that angle.

OMG, you'd totally be 'da man if you managed to figure out a way to give us complete font freedom minus jailbreak!!!!!
